Application of Ultrasonic Wave in Aluminum Molten Treatment

1. What is ultrasonic aluminum melt?

Ultrasonic aluminum melt processing equipment is a high-power ultrasonic equipment specially used in the metallurgical industry. The front end tool head of the ultrasonic vibrator is immersed in the aluminum solution in the furnace. Through the high-frequency vibration of 20KHz ultrasonic waves, it plays a role in refining and homogenizing the grains of the alloy material and accelerating the precipitation of internal bubbles, thereby promoting the consistency of the overall metallographic structure of the aluminum/magnesium alloy material. When users develop aluminum alloy materials suitable for different purposes and different characteristics, the use of ultrasonic intervention in the smelting process has become a key technical means to ensure the essential properties of the alloy material.

2. Core application functions

Grain refinement: When ultrasonic waves propagate in aluminum melt, they will produce mechanical vibration and cavitation effects, which can promote the formation and growth of crystal nuclei in aluminum melt. Significantly refine metal grains and break the coarse grain structure in traditional casting.

Uniform alloy composition: The effect of ultrasonic waves can make the composition in aluminum melt more uniform. Through stirring and vibration, ultrasonic waves can accelerate the diffusion of solute atoms and reduce component segregation.

Degassing and slag removal: The cavitation effect merges hydrogen bubbles in the melt and floats them up, accelerating the migration and overflow of bubbles in the melt; inclusions such as alumina are driven to the surface by the sound flow, which is convenient for slag removal and effectively reduces casting defects.

3. Technical advantages

Performance improvement: grain measurement is sophisticated from 200-500μm to 20-50μm, tensile power is extended via 15%-30%;

Porosity is decreased by using 70%-90%, and fatigue existence is prolonged by means of 30%-50%.

Environmental protection: replaces regular Al-Ti-B refiner, reduces slag by way of 30%-50%; no poisonous fuel emissions.

Versatility: simultaneous degassing, refinement, and homogenization, simplifying the process; suitable for pure aluminum, cast aluminum alloy, aluminum-based composite materials and other materials.

4. Summary

Ultrasonic aluminum melt processing equipment has broken through the limitations of traditional metallurgical technology through acoustic physical modification, and is becoming an indispensable key equipment in the aluminum alloy smelting industry. It provides advanced technical means for improving the quality of aluminum alloys and developing new varieties of aluminum alloys; it helps aluminum alloy materials to be more widely used in industry, vehicles, aerospace, energy, electrical appliances, construction, daily necessities, etc., creating significant economic and social benefits.
